SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 759,565, dated May 10,1904.

Application filed December '7, 1903. Serial No. 184,030. (No model.)

To all whom, 1125 may concern,.-

Be it known that LWILLIAM SOBEY, a citizen of the United States, and aresident of Racine, county of Racine, and State of Wisconsin,

Y have invented certain new and useful Improve- Vments 1n SeedMechanism, of which the followceive. single kernels of corn arrangedlengthwise within the cells and on edge. It has been found difficult touniformly charge the cells of the plate, and particularly so if the seedis not carefully selected and all round misshapen kernels discarded.

The present invention seeks to provide an improved construction of seedseparating mechanism by which the cells may be uniformly charged withoutnecessitating the careful selection of the seed; and it consists in thefeatures of construction and arrangement of 'parts hereinafter setforth, illustrated in the accompanying drawings, and more particularlypointed out in the appended claims.

In the drawings, Figure l is a plan view of the seed-can and theimproved seed-separating mechanism therein. Fig. 2 is a sectional viewthereof on line 2 2 of Fig. l. Fig. 3 is a plan View of the improvedseed-plate. Figs. I and 5 are detail sections on lines c a, and 7)respectively, of Fig. 3.

In Fig. 2 the lower portion of the body IO of the seed can or hopper isshown. The bottom of the hopper comprises an annular upstanding flange1I and a bottom plate I2, re-

movably secured to a hub 13 by a bolt 14 and winged nut 15. The bottomplate I2 is pro* vided with downwardly-extending leg portions IG, andflange 1I is provided at diametthe under side of the feed-plate.

rically opposite points with projecting lugs I7 and I8, by which theseed-can may be secured in place upon the planter-frame.

A beveled gear-ring 2O for actuating the seed-plate revolves upon aledge 2l, formed upon the bottom plate I2, and is driven by a beveledpinion 22 on a shaft 23. The annular rotating seed-plate 24 'issupported upon the outer periphery of the gear-ring 2O and is detachablyconnected thereto by interlocking lugs and notches in the usual manner.The seed-cells 25 are preferably formed by notches in the edge of theplate, and the seed-cells are elongated in circumferentialdirection,arearranged end to end in circular series, and are adapted to receivesingle kernels disposed lengthwise and on edge within the cells. 'Ihcouter open sides of the seed-cells 25 are closed by the lower portion ofthe annular bottom flange I1,- and the bottoms of the cells are closedby a horizontal ledge 26 upon the outer periphery of the bottom plateI2. The seed cells 25 are preferably formed in a depending fiange 27upon the edge of the seed-plate 24, ,so that deep cells are providedfrom which the kernels cannot be easily swept by the overly ing grain.

A feed-plate 28 is `mounted to rotate upon the hub 13 above theseed-plate. Hub I3 is eccentrically disposed within the can-bottom, sothat the feed plate or disk 28 is eccentric, as shown in Fig. 1, withreference to the seedplate 24. The eccentric feed-plate is caused torotate with the seed-plate and the actuating gear-ring by a pin 29 onthe latter, which engages a radial depending flange 30 upon The latteris provided with a downwardly-inclined or beveled flange 31, which formsthe inner wall of a feed-groove above the cells 25 of the seedplate. Theouter wall of the feed-groove is formed by the upwardly-extending bottomflange l1. l

In operation the eccentric feed-plate 28 moves to and from the cells inthe edge of the seed-plate 24, pushes the grain toward the cells anduptilts them, so that they may fall into the cells edgewise. By means ofthe bolt I4 and winged nut I5 the bottom plate 12; the

gear-ring 20, and the seed and feed plates 24 and 28 are removably heldin place upon the bottom of the can. A small plate 32 is secured tothehub 13 and extends over the head of bolt 14, so that the lattercannot fall out when the nut 15 is unscrewed.

At or near the widest portion of the feedgroove and over thedischarge-opening (not shown) is located a casing 33, within which ismounted a suitable cut-off 34. This casing is connected to the hub 13 bya piece 35. Baffles 36 and 37. also extend outwardly from the hub 13 andare connected to the upstanding bottom fiange 11 by terminal arches 38.

The parts thus far described are similar to those set forth in LettersPatent of the United States, No. 736,307, issued to the J. I. Case PlowWorks, assignee of myself, August 11, 1903.

To facilitate the ready entrance of the kernels to the cells 25 of theseed-plate of both,

regular and irregular or round kernels and to insure the uniformcharging of the cells with single kernels as they pass under thecut-off,

vthe improved seed-plate is peculiarly formed,

as indicated more clearly in Figs. 3, 4, and 5.

The seed-plate rotates in the direction of the arrows in Figs. 1 and 3.The end of the seed-cells which first passes under the cut-ofil istermed the leading end of the cell and the other the rear end. The outerleading corner of each cell is chamfered or cut away to form a bevel 39,slightly inclined to the upper horizontal surface of the plate andleading outwardly and downwardly into the cell. The upper edge of theside wall of each cell is cut away to form a taper bevel 40, leadingfrom the forward end ofthe cell and extending inwardly and downwardlytoward the rear end of the cell. As clearly indicated in the drawings,the bevel 40 is quite steep-that is to say, considerably inclined to theupper horizontal surface of the plate. Moreover, incline or bevel 40 isof considerable width at the rear end of the cell and at this pointextends nearly to the bottom thereof; but the inclined portion tapersupwardly and outwardly toward the leading end of the cell. The rearinner corner of each cell is somewhat rounded out, as at 41, so that thekernel may be securely retained thereby in the cell as it is pushedalong under the cut-off to the discharge-opening. From this rear innercorner of each cell a shallow incline groove 42 leads upward andinwardly past the rear outer corner of the cell. VIt will be observedthat the inner edge of the bevels 39 and 4() and of the groove 42 aresubstantially in line, but that the groove 42 does not extend so fardown into the cell as the steep incline or bevel 40. In operation theinclines or bevel 39 and 40, particularly the bevel 39, formed bycutting away the leading outer .corner of the cell, facilitate thecharging of the cells with kernels. rIhe cut-away portion or bevel 40enlarge the cell sufficiently,

so that round or otherwise irregularly-shaped kernels may enter thecells; but this cut-away portion tapers toward the forward end of thecell, so that the cell is not suiiiciently large to admit two smallkernels. If, however, two small kernels should enter the cell, thecut-off will engage the upper one and push it up the groove 42 out ofthe cell before the dischargeopening is reached. The groove 42 extendsonly a short distance belowl the top of the cell and does not extend tothe outer rear corner thereof, so that a single kernel lodged in thecell could not be scraped out through the groove 42 by the cut-off or bythe overlying grain. The cut-away portion or incline 40, enlarged. atthe rear end of the cell, as stated, permits round kernels to enter thecells, so as to be engaged by the rear end and carried around under thecut-ofi' to the discharge-opening.

The edges of the incline or bevel 40 and chamfer orl bevel 39 may besomewhat rounded, if desired, instead of being sharp, as shown in thedrawings, and in other respects the precise form shown should be variedwithout departure from the essentials of the invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In corn-planters, a rotary seed-plate, a series of elongatedsingle-kernel cells therein arranged end to end in circular series andadapted to receive the kernels on edge, each of said cells having theupper edges of its inner side wall cut away to form a taper bevelextending from the leading end of the cell and increasing in widthtoward the rear end thereof, substantially as described.
